Abstract: An antenna includes a first column of main radiating elements, each main radiating element configured to operate in a first operating frequency band and a first auxiliary radiating element. The first auxiliary radiating element is adjacent a first main radiating element in the first column of main radiating elements, and the first auxiliary radiating element is configured to radiate an electromagnetic wave that is substantially antiphase to an electromagnetic wave radiated by the first main radiating element.

Abstract: A radiator assembly for a base station antenna has a longitudinal central axis and two dipoles cross-arranged around the longitudinal central axis. Each dipole has two dipole arms and each dipole arm is equipped with a hook-like feeder made of a metal sheet and having a free end portion. The hook-like feeder is capacitively coupled with an associated dipole arm. The radiator assembly is compact and is easy to manufacture and assemble.

Abstract: The present invention relates to a base station antenna, comprising: a plurality of first radiating elements that are arranged as a first vertically-extending array; a plurality of second radiating elements that are arranged as a second vertically-extending array, where the second radiating elements are staggered in the vertical direction with respect to the first radiating elements; wherein phase centers in an azimuth plane for first sub-arrays of the first radiating elements are substantially the same as phase centers in the azimuth plane for respective third sub-arrays of the second radiating elements, and wherein the first sub-arrays each have a first number of first radiating elements and the third sub-arrays each have a second number of second radiating elements, the first number being different than the second number. This can effectively improve the pattern of the base station antenna.

Abstract: Multi-band antennas utilize compact multi-band dipole-type radiating elements having multiple arms, including a front facing arm and a rear facing arm that respectively target higher and lower frequency bands. These higher and lower frequency bands may include, but are not limited to, a relatively wide band (e.g., 1695-2690 MHz) associated with the front facing arm and somewhat narrower and nonoverlapping band (e.g., 1427-1518 MHz) associated with the rear facing arm. The front facing arm may extend on a “front” layer of a multi-layer printed circuit board and the rear facing arm may extend at least partially on a “rear” layer of the printed circuit board. A resonant LC (or CLC) network is provided, which is integrated into the rear facing arm and at least capacitively coupled to the front facing arm. This resonant network advantageously supports low-pass filtering from the front facing arm to the rear facing arm, to thereby support the multiple and nonoverlapping bands.

Abstract: Base station antennas are provided herein. A base station antenna includes a plurality of vertical columns of low-band radiating elements configured to transmit RF signals in a first frequency band. The base station antenna also includes a plurality of vertical columns of high-band radiating elements configured to transmit RF signals in a second frequency band that is higher than the first frequency band. The vertical columns of high-band radiating elements extend in parallel with the vertical columns of low-band radiating elements in a vertical direction.
